Preliminary bq2118

Power Minder™ Mini-Board

Features

Complete and compact charge/discharge counter

Combines the bq2018, voltage regulator, sense

resistor, and backup capacitor on a single PCB

Communicates charge/discharge information to a

host with a single-wire interface

Designed for battery pack integration

–

Less than 0.5 square inches

Small size allows it to fit in the crevice formed

by two adjacent cells

–

Low operating current

Direct connections for the pack cells and

communications port

A module development kit is also available for the

bq2118. The bq2118B-KT includes one configured mod-

ule and the following:

General Description

The bq2118 Power Minder mini-board provides a com-

plete and compact solution for charge and discharge

counting of all types of battery chemistries, including

NiCd, NiMH, or Li-Ion batteries. Designed for battery

pack integration, the bq2118 incorporates a bq2018

Power Minder IC, supply voltage regulator, sense resistor,

and backup capacitor on a small circuit board. The mod-

ule provides direct connections for the positive and nega-

tive terminals of the series cells in the battery pack, and

can fit in the crevice formed by two adjacent cells. The

bq2118 allows a battery pack to be equipped easily with

accurate charge/discharge counting electronics.

1. An EV2200-18 interface board that allows connec-

tion to the serial port of an AT-compatible com-

puter.

2. Menu-driven software to display charge/discharge

activity and to allow user interface to the bq2118

from any standard Windows 3.1 or 95 PC.

BAT+

Unitrode configures the bq2118 based on the informa-

tion requested in Table 1. The configuration defines the

battery chemistry, the number of series cells, and the

charge/discharge current. Figure 1 shows how the mod-

ule connects to the cells.
